My invention is a roof of the slate, shingle vr tile type.

An object of my invention is the construction of a roof formed of slate, shingles or flat tiles,' in which the slates are laid in such a manner as to give an improved architectural effect, especially by giving deeper shadows with comparatively thin slates than with the same slates laid in the ordinary manner. Moreover, vthe manner of laying the slates allows giving a variation to the structure and adding to the ornamental characteristics of the roof. Another object of my invention from a structural standpoint is the laying of the slates in an overlapping manner, running from one end of the roof to the other, successive roofs overlapping in opposite directions.

so that the slates are securely bound to the roof, the overlapping rows binding the lower rows and the la ers being double and triple thick in some p aces.

In one form of constructing my invention vI lay a row of slates adjacent the eaves, this y row starting at one end and each layer overlapping the side edge of the adjacent slate. The second row starts from the opposite end of the roof and the slates overlap 1n the opposite direction, the third row being a repetition of the lirst row adjacent the eaves. As

a variation of this construction the indvidf ual slates of each row are made of different lengths so as tohave a staggered effect at their lower edge. In a still further modification of the roof structure the slates are constructed of large and preferably substantially uniform size and have smaller cover f strilps secured thereon and positioned centray of each individual slate.

My invention in several of its aspects is illustrated in the accompanying drawings, in which Figure 1 is a erspective view of a simple form of my roo construction.

Figure2 is a plan view of a modification, showing the slates staggered.

Figure 5 is a section of Fig. 4 on the line 5 5 in the direction of the arrows.

Figure 6 is a perspective view of another form ofmy roof in whiclnthe rows of slatesl overlap from one side.

In the construction of Fi 1 thesupporting structure of the roof is esigua-ted by the numeral 11. This may be of any `character and made of any suitable material. The first row 12 of the slates is illustrated as starting. at the right hand end, in' which the slate 13 is the first slate laid, and the next I slate 14 overla s this, as indicated at 15, the side edge 16 op the upper slate extending towards the ridge of the rootl and at right angles to the eaves of the roof. All of the slates of this first row are laid in the same manner, that is, they may be considered as overlapping the slate to the right. These' slates are secured tothe roof structure by nails or similar fastenings through the upper edge of each slate as is the common practice.

The second row 17 starts with a first slate 18 at the left hand side of the roof and the next slate 19 thereto overlaps to the left, with its side edge 2() being atriofht angles to the eaves of the roof and leading towards the ridge. All of the slates of this row are laid in the same manner, overlapping each other to the left. In this type of roof it is not necessary that the slates of the different rows break joint, as there is no objection to the exposed edges 21 of an under row being substantially in alignment with the covered edge 22 of the row next above, etc.

The third row of slates 23 is laid in the same manner as the first row, starting from the right hand side of the roof and working towards the left hand side, the slates in this row overlapping'each other to the right. It is to be understood that each row of slates has an overlap over a lower row, as is the ordinary practice in laying slates, suiicient to prevent any back runnin of water in passing off the roof from wor ing up underneath the slates.'

A characteristic feature of this form of construction is that part of the exposed edges .of the slates, looking from the eaves towards the ridge of the roof, shows slates of one thickness, as indicated at 24, while, where the slates overlap as at 25, they show a. double thickness of slates. Manifes'tly at these double thick portions there are actually threey thicknesses of slate, measured upwardly from `the roof, and at the parts indicated at 24, there are two thicknesses of slate.

In the modification of Fig. 2 the lower row of slates 30 is indicated as being started from the left hand end; 31. The next slate 32 there.A to 'overlaps -to the left, as indlcated at 33,

a third slate 34 overlaps the second slate to the left. These slates, however, have their lower edges 35 and 36 oli'set or stepped up, that is, each alternate slate has its lower edge higher up the root than the adjacent slate on each side. In this construction it gives a desirable el'ect to have the edges, indicated at 35, in substantial alignment with the eaves of the roof, or possibly partly projecting slightly outside of the eaves of the roof and the edges 36 extending beyond the eaves of the roof. This arrangement is eected by using slates of different length, as indicated at 37 and 38, for although the slates have anolfset as indicated at 39 at their' u per edge where they are secured to the roei) by nails 40 or other fastenings, yet the lower edges have a very much greater offset or stagger than tle upper edges.

A second row of slates, designated by the numeral 41, is started with a first slate 42 on the right hand side of the roof, the next slate 43 overlapping, as indicated at 44. Such row is continued from one side of the roof to the other, building' up the roof in somewhatthe same manner as in Fig. 1. With this arrangement of slates and also using some slates longer than others, there is no distinct row of slates showing as viewed from the ground or the level of the roof, but the edges of the slates appear in a staggered relation, that is, adjacent slates having their lower edges either towards the eaves or towards the ridge of the roof. The roof built up in this manner also has sections with a single and a double thickness of slate showing from the edge, thus giving a variation in the appearance and in the shadows formed by the slates.

In the construction of a roof as'illustrated in Figs. 4 and 5, the lower row 50 of slates is indicated as having the lower edges 51 in alignment, the rst slate of the row indicated at 52 being started on the left hand side of the roof and the succeeding slates overlapping at the left, as indicated at 53. Before laying the second row, there are laid-a series of ornamental pieces 54 which are positioned substantially in the middle of the exposed part of each slate and have their lower edges 55 at any suitable distance between the lower edges of each of the rows of slates.

The second row of slates 56 also has its lower edge parallel to the, lower edge of the irst row, and the lirst slate of this row, indicated at 57,- starts on the right hand side of the roof, and the next slate 58 overlaps 4to the right, as indicated at 59. This type of roof has the same characteristics in laying the'main slates as set forth in connection with the laying of the slates in Figs. 1, 2, and 3, and has in addition, the ornamental strips 54. The ornamentalstrips are secured by nails 60 which are driven into the roof structure 11 slightly above the nails 61 which hold the m'ain slates of each row. This arrangement gives a slight open space on each side of the ornamental pieces as indica-ted at 62, allowing a certain circulation of air underneath the slates, adding materially to the coolness of the roof when used in hot climates.

It is obvious that many other changes may be made in the design of roofs, using the principles above mentioned of overlapping the dii'erent rows of slates when working in different direct-ions, considered from the sides of the roof, and that various ornamental third row 74 is also built up Ain the saine manner.

It is to be understood, of course, that the slates may be built so as to overla to the left. This type of roof, however, invo ves the feature of the slates of each succeeding row, all overlapping in the same direction as in the adjacent rows. In all the constructions it is also to be understood that the slates may be arranged to have an overlap, that is, to break joint much in the same manner as in the ordinary slate roof.

Various changes may be made in the principles of my invention without departing from the spirit thereof, as set folth in the description, drawings and claims.
